This is the third Tiele system that I have purchased. Generally I have been very pleased with the quality and reliability of the product. However, the reason that I purchased this particular package was that my transformer burned out after just 1 year of heavy use (with 150 watts). So instead of just purchasing a new transformer, I decided to purchase the pack with the additional rails and hardware. This way I will be prepared for a more extensive installation next time. The life of this transformer will determine if I purchase another.

Decent item, was what I needed to complete the look I was going for. I don't understand why a few pieces of metal cost so much though.

I have two track lights in my yoga studio. I have the lease for one more year, and one of the tracks shorted out. The manufacturer no longer makes this particular track, and I was looking at the expense of now replacing TWO tracks. The manufacturer also did not sell the replacement parts. So either way, this would have cost me far more than I was willing to spend for a remaining year in the current space. The replacement hardware fit like a charm with the existing track equipment, thus saving me over $500! Thank you!

Original purchased kit did not last, I kept having problems, lights kept going off, it was a nightmare. Tiella was not very helpful, I called several local companies that Tiella said should have the items to no avail. I was happy to find the replacement here on line.
The new transformer and track were installed over a month ago and all seems well for now.
